This invention relates t stoppers 101' coutainerS of beverages and other liquid commodities.

More particula1ly the invention relates to 5 a, stopper in the form of a disk which is used with a inetal crown 01' cap for the purpose cf stoppering containers such as bottles anal .ars.

J Sonde of the objects o1": the prcsent inven- 19 tion are: to provide a stopper 0f the indicated character which Will not afl'ect the color sind the flavor of the beverages and other liquids stoppered; to proiride a stoppen 0f the indicated character, 0f material which will not carry With it foreign matter 01 particles apt to fall into the stoppered beverage; to provide a stopper of the indicuted character which 'has exceptional resiliency enu: bling the stoppering 0f beverages and other 20 liquid commodities without breaking the containers; und to achieve' econ0my in thc 01 may be on the s1deconnng m cont&ct W1th 1nanufacti1re of stopp ers of (bis charactcr.

In accordance With the present invntion use is made of ochroma lugopus, commonly called balsa wood. Balsa W00d has a cellular texture with the absence of fibers in its structure. The resiliency 0f balsa wood is shown by the test in which a three'inch cube thereof, conipressed to one-half inch, under a load of' eight to' ten thousand pounds, A When released Will return 130 a height of one und thrce-fourths inches to two inches, und ics resiliency is not altered 01' afl'ected by subsequent compressions. Its muss possesses the color 01 appeurance and flavor of many bev'erages such as mineral water, lithizi water und carbonated water. This material is composed of nurnberless cells which contain ai1 und not wenn holes filled with decayed granules such as are found in cork, und thercfore will not deposit foreign substance int0 the stoppered beverage.

F ig. 3 is a perspective view of a modified fotm of stoppen As before stated, .the stopper of the present u chemical composition Which will not aflect,

invention is made 0f balsa W00d beca'useof its chemical composition molecular arrangement, and modulus 015 elasticity. The stopper will be 1nadc in the form of a disk which may be used as a lining with ametal crown 01 cap f01' the purpose of stoppeting containers such as bottles and jars. The

disk designatcd 10 will be made 0f any prefcrrcd thickncss und diameter. In accordance with the p1esent invention the disk may be saturuted 0r impregnated wholly 01" partly to render the saine liquid proof. It is also to be understood that the disk 10 1nay bc rende'red liquid proof by the provision 0f onc 01' moredaminations of' parch mcnt, puper, 01 ot-her liquid proofing material, substance 017 solution, 011 one 01 both sides of t-he disk, such laminations heilig dcsignuted 11. The laminated sid e 0f the disk muy be disposed contiguous the crown 01' cap, when ananged in the crown o1 cap,

the liquid.

It is also 300 be understood that the disk may bc ti'eated With a preservative such as paraflin glycerinc, 01' other substancesor materials, with Which the disk will be suturuted or impregnated wholly or partly. y

In Fig. 3, the disk 10' of balsa wood is impregnatcd 01' hus applied along its marginal edge a resilient material o1 filler 0f rubber 0r rubber compound, as indicatcd at 14. A stopper 0f this form Will withstan d considerable pressure und se1ve t0 an exc;eptionally tight seal.

I claini:

1. A stopper consisting cf a disk 0f balsa wood und a. lsunination of liquid proof substance.

2. A stopper consisting of a disk 0f bulsa wood impregnated with a. preseivatimsubstance.

3. A st-opper consisting of a disk 0f lmlsu wood and laminat-ions of liquid proof muterial respectively on opposite sides thcreof.

4. A stopper consisting of a disk oi balszi wood having its marginal edge portion impregnated with a resilient materiql.
